Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed May 18, 1912. Serial No. 698,219.

which the following is a specification.

This invention relates to improvements in swings, and particularly to improvements in details of features of the structures illustrated and appearing in my Patent No. 7 69,298 of September 6, 1904, and my Patent No. 8ei8,534 of March 26, 1907, for swings.

The objects of this invention are: First, to provide an improved construction of double rocker for such a swing. Second, to provide in such devices improved connecting means for such rockers or swinging parts to avoid the squeak and insure ease of action.

Objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow.

I accomplish the object of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims. a j

A structure whichis a preferred embodiment of the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a side elevation view of a swing embodying my improvements. Fig.

II is a detail end: elevation of the structure.

appearing in Fig. I, the upper portion. of

, the seat part being broken away. Fig. III

is a detail sectional elevation taken on a line corresponding to line 3.3 of Fig. II. Fig. IV is a detail perspective view of the double headed rocker part by itself. Fig. V is an enlarged transverse detail sectional view of the rocker part taken on a line corresponding to line 5-5 of Fig. II. Fig. VI is an enlarged detail longitudinal sectional view of the tie rod for the pairs of rockers showing an economical feature of the construction. Fig. VII is a detail'view showing the motion of the rocker in dotted lines. Fig. VIII is an enlarged detail view, partially in section, showing the pivotal connection of the-swing platform to the rocker section.

In the drawing, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and similar numerals of reference refer to similar parts throughout the several views.

Considering the numbered parts of the drawing, I will state that the general structure 18 very similar to that appearing in my aforesaid patents.

The platform or base is made up of side rails 1, connected by suitable cross bars 2, and each rail provided with suitable ways 3, having an outer raised flange 5 toward the outer side. A pair of chairs-or seats 6 are disposed above the platform and are connected by frame bars 7 toward each side of theplatform, being supported by a pair of legs or uprights 8-9 secured by suitable means. Diagonal brace bars 10 couple these various uprights and bars together, and serve to provide supports for the backs of the chairs or seats.

Side bars 11 arebeneath the seats 6, and are provided with suitable ways 12 for receiving the upper rocker 4 of the double rocker at each side. Curved bars 13 connect the lower ends of the standards or legs 88 together and engage under suitable guide lugs 14 on the side 8 of the frame bars 1.

A platform 15 is disposed beneath and between the chairs, and is supported by obliquely upwardly-projecting arms 1 15, which engage over transverse tie rods 17 between the pairs of double headed rockers at each end of the platform. These arms 15 are perforated by large circular openings 16, which cut through the under edges of ,hooked over the rod 17. Owing to the fact that this aperture is much larger than the rod 17, the tendency of the two parts to slip the one upon the other and consequently squeak is substantially obviated. The bearing will be effective, of course, in avoiding noise if the aperture is not open at one side. This transverse tie rod couples the central bars 18 between the double rockers 4, l. The tie rod 17 is provided witha screw thread nut 20 on the outside, and with a cupped washer or head 19 on the inside, which engages projections 21 struck up from the rod 17, as clearly appears in Fig. VI. This provides a very cheap and economical construction, andone in which there are no rough parts exposed, and which is also very strong and durable. The tie rod 17 coiiperates with the heavy wood bar 22,

secures the double rockers together in pairs as indicated.

The double rockers 4, i are each retained a on the central bar 18 by suitable braces 24, which are secured by rivets 25, and are bent outwardly and conformed to the shape of the rocker at 26, to which they are secured by rivets or by other suitable means. The rockers r and 4L are made of round back angle bars, suitably curved, so that they fit very nicely into the ways on the platform below, and the seat frames above. They are not quite true circles, but are a little fiattened and tend, when the swing is not being actuated, to bring the swing to anormal central position.

A brace bar 27 extends between the upperrear portions of the rockert, 4L, and is secured in place by clips 28. A similar bar 29 is disposed between the rear portions of the rockers 4, 4, and is retained by clips 30 at each end. Loops 32 are on the upper sides of each of these bars and serve as keepers for the-stop links 33 and 34. A stop link 33, with a loop 33' embracing the brace rod :27, is pivoted at 35 to the seat bar 11. stop link 34 is pivoted at 36 to the base and is provided with a loop 34 which embraces the lower brace bar 29. These stop links permit the necessary swinging motion, and yet serve as very effective stops to prevent undue motion between the parts. The structure insures alinement of the rocker heads, and prevents friction by insuring proper register of the moving parts. The relation of these stop linksdefinitely appears from an inspection of Fig. III.

This invention is an improvement, primarily, of the double headed rocker structure and swinging. parts and their connections, and I have merely described the other parts of the swing so that the true relation witnesses.

of this double headed rocker, swinging parts and connections may definitely appear. The structure can be greatly modified without departing from my invention.

Having thus described my inventiomwhat I claim as new and desire to secureby Letters Patent is:

bar connecting the centers of said angle 7 bars and brace barsconnected at their .cen'

ters to the center of said cross bar and havi ingtheir ends inclined outwardly and connected to the ends of said angle bars, and

suitable cross rods connecting the rocker heads together, all coacting substantially as described for the purpose specified. 7 i

2. In a swing structure, the combination of a suitable platform, a seat disposed above the same, a double headed rocker having a rocking engagement with said platform and g supporting saidv seat, said double ,headed rocker comprising a pair of rocker heads, each rocker head being formed of a pair of curved angle bars connected together by suitable brace bars, upper and lower, tie-rods connecting said rocker heads, andupper and lower links comprising rods pivotally connected to the seat and platform respectively and embracing the upper and lower tie-rods to limit thermovement ofIsaid rocker head and insure the alinement thereof, all coacting substantially as described for the purpose specified. 1 7 V Inwitness whereof, I have hereunto set my hand and seal in the presence of two 7 ALLEN P.
